Abstract
The invention relates to a dart head for a toy dart. The dart head comprises a body having an enlarged head portion integrally formed with a stem portion longitudinally extended from the head portion, wherein the head portion is hollow. The invention also relates to a toy dart comprising a dart body connectable with the dart head as described.
Claims
exact text as granted — not AI-modifiedThe invention claimed is:
1. A method of manufacturing a dart head for a toy dart, the dart head comprising a body having an enlarged, hollow head portion integrally formed in a single, continuous piece with a stem portion longitudinally extended from the head portion, the method comprising the steps of:
providing a male mold and a female mold having at least a first female mold part and a second female mold part, the male mold and the female mold cooperatively define a molding cavity therebetween;
injecting a flowable polymer into the molding cavity between the male mold and the female mold;
solidifying the polymer between the male mold and the female mold to form a solidified, molded polymer;
separating the first female mold part from the molded polymer; and
mechanically releasing the molded polymer from the second female mold part and the male mold;
wherein the molded polymer is of sufficient resiliency such that it is deformable to thereby overcome the male mold upon the mechanically releasing step without breaking apart; and is restorable to its original shape after the mechanically releasing step.
2. The method of manufacturing the dart head according to claim 1 , wherein the step of mechanically releasing the molded polymer from the second female mold part and the male mold comprises first disengaging the molded polymer from the second female mold part, and subsequently, releasing the molded polymer from the male mold.
3. The method of manufacturing the dart head according to claim 2 , wherein the male mold is movably connected at the second female mold part, and is adapted to move away from the second female mold part thereby disengaging the molded polymer from the second female mold part.
4. The method of manufacturing the dart head according to claim 1 , wherein the male mold comprises a pushing means adapted to mechanically push the molded polymer off from the male mold.
5. The method of manufacturing the dart head according to claim 1 , wherein the male mold comprises at least one male mold member having an enlarged head connected with an elongated stem, with the enlarged head being substantially conform in shape with the first female mold part, and the elongated stem being substantially conform in shape with the second female mold part for molding the dart head.Join the waitlist — get patent alerts
